Title: Brush roll apparatus for continuous treatment line of metal strip
Inventor: FUJINO SHINJI
IPC: A46B7/10
Filed: 1989-09-28
Abstract: PURPOSE:To prevent the adhesion of washing oil to an oil uncoated material by implanting a brush in the peripheral wall part of a roll shaft and providing jet orifices turned to the brush thereto. CONSTITUTION:A brush roll 2 is rotated in the direction reverse to a strip passing direction in contact with a strip 12. Washing oil is injected to a brush 4 from the jet orifices 17 of a roll shaft 2'. The foreign matter such as dust bonded to the surface of the strip 12 is removed by the brush 4 and washed off by the washing oil. The washed strip 12 is drained by a wringer roll 3 to move to a post-process as a cleared strip. The contaminated washing oil is accumulated in the contaminated oil tank 6 provided to the bottom part of a housing 5 and filtered by a filter 8 through a contaminated oil pump 7 to be recirculated and reused.
